To all whom it may concern: v embodiment'of the'invention is 'shown,lit, Be it known that I, CHARLES D. DALLAS, may be mentioned that I have illustrated an a lcitizen of the United States, residin at arbol'adaptedV for winding strip `metal,. it VVinnetka, in' thc county of Cook and tate being understo'od,"however, thaty the, vna'- y of Illinois, Ahave invented certain` new and terial to be'wfound maybe such as is desired. 55 useful Improvements in Winding' Arbors, As shown, 1 represents a' shaftf'of the de-y of which the following is a description. sired size and driven 'in any suitable man- My invention belongs to thatv general class ner, preferably by'power, the same'being'rd of devices known as arbors, and relates--partatably supported by af bearing 2 lof any ticularly to a winding arbor for winding or desired machine, formingno partv of the 60 f coiling any desired material for any desired present invention. "The shaft 1 carries the urpose. The invention has among its obarbor' parts 3,'of which there may be any'y )ects vthe production of a! device of the kind desired number, three arts being shown, described that is simple, convenient, efiiwhich may be contracted) or expanded asdecient, compact, durable" and satisfactoryY for slred. p j

To this end my invention consists in the as most clearly shown'in Fig. 1. I have novel construction, arrangement and comshown pins 7 carried by the parts 3 and probination of parts herein shown and det jecting into'the spaces 4, and vin this conscribed, and moreparticularly pointed out nection it may bevmentioned that itfiskimin the claims. material whether the space 5 is arranged on 85 In the drawings, wherein like reference part 1 or part 3, this depending upon which characters indicate like or corresponding part carries the pins?.

Fig. 3 enlarged to more clearly show the The arbor parts may be maintained on the construction. K A y shaft 1 41n any desired manner. As shown, a v In the drawings, in which the preferred collar 8 is arranged onthe shaft, the same loo engagement with the arbor, as well as to- Inove the entire arbor on the shaft toward the free end. Arranged on the opposite end of the shaft 1 is a member 11, this being preferably constructed to engage the threaded end 12 of the shaft. Member 11 is provided with a flange 13 arranged to fit over and engage the flange 14 on the parts 3 and limit the expansion at that end, Referring to Fig. 2, it will be noted that one or more of the parts 3 are provided with slots 15, and I have shown members 16 mounted on the arbor, the number of these depending upon the size of the strips to be wound. I have also shown the parts 3 provided with an internal rib 18, which tends to strengthen the parts. In using the device, assuming that strips are to be wound in coils, thel same being of widths substantially equal to the distance between the plates 16, 1t may be mentioned that the material may be drawn directly from the machine, cutting the strips from a large piece or plate. The extreme free ends of the strips may be inserted in the desired slot 15, the plates 16 being pushed up so as to form spaces for they coils. the same serving to feed the strips evenly on the arbor and maintaining the coils flat atl their faces. The arbor isv in its expanded position substantially as shown in Fig. 1. If now shaft 1 is driven, the strips will be wound on the arbor until the desired amount of material is coiled or rolled. If the end of the strip is reached or the strip severed, the coils will be contained on the arbor. The part 11 may then be turned on the threaded end 12 of the shaft so that the arbor-.may

, be moved away from` the support 2, spring 9 tending to push the whole arbor toward the end of the shaft. A slight` movement of the arbor parts on the shaft 1, however, moves the parts 6 bearing on the faces of parts et'.` Owing to the inclination of the faces between the parts, the parts 3 may then4 be contracted thereby relieving the pressure caused by the winding of the coil tightly on the arbor. The movement of the` parts 3 being slight to permit the contraction, flanges 8 and 13 will remain in engagement-,with the arbor parts, maintaining them assembled. The plates 16 and coils of material may then be readily removed from the arbor by sliding the same over the end. Part 11 may then be turned up, again expanding the arbor to its winding adjustment. The recesses 6 permit a certain amount of clearance of the pins 7.

It will thus be obvious that the coils may be readily removed from the arbor without difficulty and in but a. moments time, and

without the slightest danger of telescoping, as it may be termed, or disarranging the rolls or coils. The device permits the material to be very tightly and uniformly wound and all of uniform size.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described, or uses mentioned.

What I claim as new and desire to secure by Letters Patent is: r j

1. A winding arbor, comprising in cornbination, a drive member, an expansible arbor member carried ythereby and removable longitudinally thereof, means always entirely within the periphery of said arbor for radially expanding it, and yieldably held means exteriorly of said arbor member for limiting the expansion of said arbor member. v

2. A winding arbor, comprising in combination, a drive shaft member, an arborv shell of a plurality of circumferentially ar.- ranged sections remowably carried thereby, axially spaced cam faces projecting inwardly from said arbor sections, cam faces projecting outwardly of. said shaft and cooperable with first said cam faces t-o prevent independent rotational movement between said arbor and shaft, means for moving one of said shaft members longitudinally of the otherto radially expand said shell member, and a rib on said arbor shell intermediate its cam faces to reinforce sa'id shell and limit the radial in- 105 ward movement thereof.

3. A winding arbor, comprising in combination, a drive shaft member, an arbor member of a plurality of circumferentially arranged sections surrounding said drive member and carried thereby, cooperating cam faces on both said members, means for adjustably moving said arbor sections longitudinally of said shaft to engage said cam faces and expand said arbor member, means v longitudinally movable on said shaft and enclosing the ends of said arbor sections `for limiting said expansion, and means for yieldably pressing one of said end-enclosing means axially against said arbor member to releasably hold said arbor member within the other end-enclosing means.

4. A winding arbor, comprising in combination, a rotary drive shaft member, an arbor shell of a plurality of circumferentially arlanged sections removably carried thereby, axially spaced cam faces projecting inwardly from said arbor sections, axially spaced cam faces projecting outwardly of said shaft and cooperable with said arbor 10 arbor shell intermediate its cam faces to re inforce said shell and limit the radial inward movement thereof.

In testimony whereof I have hereunto signed my name in the presence of two subscrbing Witneses.
